Patent GB-1288184-A (GB)
IPC: H04L27/144
Filed: 1971-01-12
Abstract: 1288184 Digital transmission; FSK systems MEL EQUIPMENT CO Ltd 12 Jan 1971 1398/71 Heading H4P In an F.S.K. receiver having separate mark and space circuit branches each including a signal detector followed by an assessor which compares the signal level relative to that of immediately preceding signals, the output of the two assessors are combined, and a bias signal dependent on the relative signal levels at the inputs of the assessors is developed which is combined with the outputs of the assessors. The biasing networks, which are symmetrical, comprise for the mark branch diodes D1-D4 and potential divider R5, R6, non-linearity being provided by a diode D5 which provides a cut off at about 0À5 volts. A similar arrangement is provided for the space branch providing a bridge network coupled across one diagonal by resistors R10, R11 and an earthed integrating capacitor C3 the potential from which is combined with those from known signal assessors 6M, 6S through resistors R24-R26 at the input of an amplifier 7. The signal assessors 6M, 6S are set to a judgment level half way between the noise level and the desired signal plus noise but without bias if the system is in an idle state for a period exceeding the time constant of the circuit, the level will reduce substantially to zero and the system will not only respond to interference but will also distort the first signal. The biasing network however will provide a threshold level to the amplifier 7 hence the first signal must exceed this level before this can be detected by a level detector (8, not shown) following amplifier 7. In continuous working conditions signals appearing at inputs to networks 21, 23 are opposed hence bias tends towards zero. It is stated that optimum results are achieved if networks 21, 23 are arranged that the relation between input and output signals below a given level is different from those above this change point being provided by diodes D5, D10.

Abstract: 1295745 Automatic current control INTERTRADE WARENVERKEHRSGESELLSCHAFT HILD & CO K G 16 Sept 1970 [17 Sept 1969 15 June 1970] 44153/70 Heading G3R The alternating current through a load 24 such as an electric cooker is maintained at a desired average value by control of a TRIAC 27 in series with the load 24 and AC source AB, such that when the current sensed by a resistor 40 is below a predetermined threshold value the TRIAC 27 is fired at the start of each half cycle but when the threshold value is exceeded a thyristor 39 is fired to prevent firing of the TRIAC 27 for a number of cycles dependent on the excess. During negative half-cycles firing current for the TRIAC 27 flows by way of members 31, 32, 33, 37, 38, the subsequent conduction of the TRIAC causing a capacitor 29 to charge via members 35, 36. Discharge of the capacitor 29 fires the TRIAC 27 at the start of the following positive half-cycle. The signal from resistor 40 is adjustable by an autotransformer 47 and a potentiometer 46 and is rectified by a diode 42 to charge a capacitor 43. Thyristor 29 can only be fired during negative half cycles and, when fired, prevents charging of the capacitor 29 and hence the firing of the TRIAC 27 during a following positive half-cycle. The voltage stored on capacitor 43 determines the length of time during which firing of TRIAC 27 is prevented, decay of this voltage to a predetermined value allowing the resumption of normal firing operation.

Abstract: 1301869 Jetting-up; tens transfer device RICOH KK 20 Oct 1970 49783/70 Headings G4B and G4D A device for use in mechanical calculating apparatus has a number of movable parts 9, 14 each mounted in a radial slot 2 in a rotatable disc 1, each movable part being displaceable in an axial plane of the disc and having a body 9 with a notch 11 which abuts the end 10 of the slot 2, and a plurality of notches 12, 13 selectively engaged by a locking device 5, which is comprised by an annular coil spring or similar resilient member, e.g. of rubber or plastics, to maintain the movable part in one or another stable service position and also to retain the movable part in the slot 2. The number of movable parts and stable service positions is determined by the particular function, the device is to perform, e.g. value actuator, carry over mechanism or mechanical memory. In the particular embodiment described, the device has nine movable parts 9, 14 (Fig. 2, not shown) and is intended as a value actuator. A movable part is tilted in the direction of arrow 15, to a working position from the normal position, as shown, by the action of an axially and angularly displaceable control member comprised by a cam 16 integral with a hub 17, which also carries gearing 18 and a ciphered drum 19 (see also Fig. 3, not shown). The number of parts 9, 14 moved into a working position depends on the angular displacement of the control member, and hence the positioning of cam 16 relative to the movable parts, before the control member is axially displaced. This angular displacement may be achieved by a rack meshing with the gearing 18. The extension part 14 may be in the form of a cam, gear tooth or truncated gear tooth. To provide a carry-over drum several discs 1 are arranged side-by-side, each disc having one movable part 9, 14, and the movable parts of the various discs being arranged on a helix.

Title: Automatic bar feeding apparatus
IPC: B23B13/02
Filed: 1970-09-29
Abstract: 1322923 Bar stock feeding AZUMA SANGYO CO Ltd 29 Sept 1970 46325/70 Heading B3B In automatic bar feeding apparatus in which a push rod 21 is movable under the influence of gravity on a weight 9 to advance bar stock, the motor 25 drives a member 43 in the feeding directions such as to restrain movement of the bar stock under gravitational force during that part of the advancement which corresponds to machining of the bar stock. As shown the apparatus comprises push rod 21 in a guide tube 2. A wing 19 on push rod 21 is connected by cable 17 to a stepped pulley arrangement 13, 15 from which a weight 9 is supported. In operation.-With the push rod fully retracted, bar stock is fed into the guide tube 2 by a known mechanism. As a result a motor 25 is actuated to rotate a drive sprocket 7 of a chain 5. Mounted on chain 5 is a member 43 whose nose portion 45 restrains push rod 21 from movement due to the suspended weight 9, by engaging the wing 19. As chain 5 moves, counterclockwise in the figures, push rod 21 is permitted to move under the force on weight 9. A cam plate 57 on push rod 21 then actuates a linkage 79, 77, 67, 75 (Fig. 5) to cause jaws 59, 61 to grip the bar stock 23. Then a cam plate 41 (Fig. 4) on the apparatus frame 1 causes a pivoted arm 50 to be placed in an operative position in which it engages behind wing 19. Arm 50 is mounted on the member 43 on chain 5; thus the push rod is now driven to cause its end recess 65 to engage over the end of the stationary bar stock 23. Cam plate 57 then allows the jawactuating linkage to open the jaws, whereupon the push rod advances under the influence of weight 9 until wing 19 abuts the moving nose portion 45 which then governs the advance of the push rod. Wing 19 operates limit switch 37 (Fig. 1) to cause a machine tool, e.g. automatic lathe, to close its chuck for machining. During machining the chain 5 continues to move, while the bar stock is fed, under gravity on weight 9, in steps through the machining cycles. Nose 45 will limit the movement of the push rod after each step. Motor 25 is stopped when member 43 trips limit switch 35. Eventually wing 19 actuates limit switch 31 to cause motor 25 to reverse the motion of chain 5. Nose 45 then causes wing 19 and push rod 21 to retract. During this motion plate cam 57 once again actuates the gripper jaw linkage to grip the bar stock scrap end to remove the latter from recess 65 as push rod 21 continues to retract. Finally member 43 trips limit switch 33 to stop motor 25, and the push rod is engaged by a stop pin 53. In a modification (Fig. 7, not shown) the gripper device is replaced by an ejector mechanism.
